Answer:

6.3

Step-by-step explanation:

This is because when you do 9/5 you get 1.8. Then you multiply 1.8 by 3.5 and get 6.3

If two linear regression models have the same number of explanatory variables, a model with an R2 value of 0.45 is a better pred
icang [17]

Answer:

False

Step-by-step explanation:

Given that two linear  regression models have the same number of explanatory variables

First model has coefficient of determination as 0.45 while other

0.65

we know that R^2 is the proportion showing the variation of dependent because of variation in independent variables.

Hence a higher R square is always better because it ensures more linearity and hence more accuracy in the regression equation.

Hence 0.65 model is better than 0.45 model.

The given statement is false.

Triangles A B C and N M Q are shown. Sides B C and N M are congruent. Angles A B C and Q N M are congruent. Angles B C A and N M
Ugo [173]

What would be included to prove both triangles are congruent by the AAS theorem is: B. AB ≅ QN because they are both opposite a right angle.

<h3>What is the AAS Congruence Theorem?</h3>

The AAS congruence theorem states that two triangle are congruent if both have two pairs of corresponding congruent angles and a pair of non-included corresponding congruent sides.

In the image given, since AB and QN both lie opposite a right triangle, then they are congruent to each other.

Therefore, to prove both triangles are congruent by AAS theorem, what would be included is: B. AB ≅ QN because they are both opposite a right angle.

cylinder has a height of h inches and a diameter of 3 inches. What expression gives the volume of the cylinder in cubic inches?
pashok25 [27]

Answer:

The expression that gives the volume of the cylinder in cubic inches is V=\frac{9\pi h}{4} \:in^3.

Step-by-step explanation:

The base of a cylinder is a circle, the area of that circle is given by the formula:

area = \pi r^2

Multiplying by the height h we get that the volume of a cylinder is

V=\pi r^2h

where:

π = Pi

<em>r</em> = the radius of the circular end of the cylinder

<em>h = </em>height of the cylinder

We know that the cylinder has a height of <em>h</em> inches and a diameter of 3 inches.

The radius of a circle is half the diameter and the volume is:

V=\pi (\frac{3}{2}) ^2h=\frac{9\pi h}{4} \:in^3
